IMPROVEMENT IN CHEESE-MILLS.

Specification forming part of Letters Patent No.

151,927, dated June 9, 1874; application filed Febrtary 1o, 1874.

To all whom it may concern:

Be it known that I, LoUrs P. SMITH, of Middletown, in the county ofDauphin and State of Pennsylvania, have invented a new and ImprovedCheese-Mill, for making cottage-cheese or smear-case, and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings, making part of thisspeciiication- Figure 1 being a top view of the machine; Fig. 2, avertical section thereof through the axis ofthe driving-shaft; Fig. 3, avertical section ofthe same in a plane at right angles to the section inFig. 2 5 Fig. 4, view of a part detached.

Like letters designate corresponding parts in all of thetigures.

The purpose of my invention is to grind or rub the curd of sour milk formanufacturing cottagecheese or smear-case, audits construction issubstantially as represented in the drawings and herein described.

A rectangular box, A, of proper dimensions, is formed open at the top,and closed at -the bottom withsheet-tin or other suitable sheet tin maybe entirely perforated with fine holes; but I prefer to have only thelower middle portion B of the .perforated sheet metal, while the sideportions C C are of the common impcrforatcd sheet-tin. Where theimperforated and the perforated parts are united there areslightly-raised seams or ridges a a on the inside. In the lower part ofthe box A is located a cylindrical wooden roller, D, reaching at itsends close to the adjacent sides of the box, and at its peripheryfitting quite closely to the adjacent sides of the box and to thesemi-cylindrical bottom, but allowing a narrow space between suicient topermit the curd, iu small quantities at a time, to pass down under theroller. The journals of the roller-shaft E turn in bearings b b in thesides of the box, the said journals being somewhat less in diameter thanthe bearings, especially from top to bottom, as shown in Fig. 4, so thatthe roller may play a little up and down and sidewise in the box, inorder to regulate the feeding down of the curd, and to press by itsgravity upon the same, thereby assisting the grinding action of itsperiphery upon the curd, and helping to squeeze the curd through theperforations of the tin plate. The shaft E is provided with a winch orcrank, d, at one end, and extends through the center of the roller, towhich it is secured by means of a screw-thread, f, on its periphery,turning into a xed nut, g, in one end of the roller. Thus the shaft canbe readily withdrawn for removing the roller from the box, and cleaningthe same and the interior of the box, and for reinserting and mountingthe roller. The box A is provided with supporting-arms h h h h,extending horizontally from near the bottom thereof, or with equivalentmeans of support.

Thus constructed, the machine operates as follows: The curd, dry ormixed with cream, is first put into the box, over and around the roller,and the box is placed over any suitable vessel to receive the groundcurd, and rests, by its arms h h 7L h, upon the edges or sides thereof.The crank d is turned in either direction, and the roller D causes thecurd to pass down in small quantities atatime, at onel side of itsperiphery, and vbetween it and the sheet-metal bottom of the box, theimperforated parts C C'of which serve as rubbing-surfaces, and theperforated part B allowing the ground curd t0 pass through it into thereceivingvessel beneath, being assisted in the discharge by the weightof the roller in its enlarged bearings. The seams or ridges a a serve toscrape the curd from the roller, and to prevent its ascending at therising side thereof. These seams also serve to strengthen the bottom ofthe box.

Ahat I claim as my invention, and desire to secure by Letters Patent,is-

l. A mill for preparing cottage-cheese or smear-case having a perforatedor reticulated bottom or surface, B, in combination with a crusher, D,arranged to move in near proximity to the said perforated surfaces,substan- Vtially as and for the purpose herein specified.

2. A mill for preparing cottage-cheese or smear-case having a roller, D,which turns in loose bearings over a perforated or reticulated bottom,B, as and for the purpose herein specified.
